HarmonyOS 鸿蒙Next中应用内开启位置信息权限

问题1可以通过geoLocationManager.isLocationEnabled接口判断位置服务是否已使能。

问题2：

我这边用的麦克风权限进行的测试，下面是授权:

let context: Context = getContext(this) as common.UIAbilityContext;
let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
// requestPermissionsFromUser会判断权限的授权状态来决定是否唤起弹窗
atManager.requestPermissionsFromUser(context, permissions).then((data: PermissionRequestResult) => {
let grantStatus: Array<number> = data.authResults;
let length: number = grantStatus.length;
for (let i = 0; i < length; i++) {
if (grantStatus[i] === 0) {
// 用户授权，可以继续访问目标操作
} else {
// 用户拒绝授权，提示用户必须授权才能访问当前页面的功能，并引导用户到系统设置中打开相应的权限
return;
}
}
// 授权成功
}).catch((err: BusinessError) => {
console.error(Failed to request permissions from user. Code is ${err.code}, message is ${err.message});
});

判断是否授权：

async onRemoteMessageRequest():Promise<boolean> {
let flag:boolean = true;
let callerTokenId: number = rpc.IPCSkeleton.getCallingTokenId();
console.log("RpcServer: getCallingTokenId result: " + callerTokenId);
let atManager: abilityAccessCtrl.AtManager = abilityAccessCtrl.createAtManager();
try {
    let res:number = await atManager.checkAccessToken(callerTokenId, "ohos.permission.MICROPHONE")
    if(res == -1){
        flag = false;
    }else{
        flag = true;
    }
} catch (err) {
    console.log(catch err->${JSON.stringify(err)});
}
return flag;
}

问题3：

let want: Want = {
    // 配置被分享文件的读写权限，例如对被分享应用进行读写授权
    // uncomment line below if wish to implicitly query only in the specific bundle.
    bundleName: 'com.huawei.hmos.settings',
    abilityName: 'com.huawei.hmos.settings.MainAbility',
    uri: 'application_info_entry',
    parameters: {
        'pushParams': 'com.example.startabilitytest'
        // 这里写上自己应用的包名在APPscope的app.json文件里
    },
    // 'action': 'ohos.want.action.viewData',
    // // entities can be omitted.
    // 'entities': ['entity.system.browsable'],
    // 'uri': 'https://www.test.com:8080/query/student',
    'type': 'text/plain'
}
this.context.startAbility(want)
.then(() => {
console.info('Invoke getCurrentBundleStats succeeded.');
})
.catch((err: BusinessError) => {
console.error(Invoke startAbility failed, code is ${err.code}, message is ${err.message});
});
